A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .

A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]
Mohs hardness kit, containing one specimen of each mineral on the ten-point hardness scale. The Mohs scale (/ m oʊ z / MOHZ) of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of minerals through the ability of harder material to scratch softer material.
The three tables should be united into one, with side-by-side Vickers, Brinell, Rockwell and megapascal values. 82.131.210.162 10:47, 16 June 2008 (UTC) Yes, done. Values should be taken as very approximate. I personally do not trust them. Materialscientist 07:43, 28 September 2009 (UTC)
By comparison, just 6.7 percent of participants who didn’t have daytime sleepiness developed MCR. What is motoric cognitive risk syndrome?
When testing coatings, scratch hardness refers to the force necessary to cut through the film to the substrate. The most common test is Mohs scale, which is used in mineralogy. One tool to make this measurement is the sclerometer. Another tool used to make these tests is the pocket hardness tester. This tool consists of a scale arm with ...
Will Brigham Young come in behind Boise State? Almost definitely. No. 6 last Tuesday, the Cougars should land no higher than No. 13, one spot or more behind Boise State, after losing 17-13 to Kansas.
